I know, but I find it confusing, and it seems others do too (eg this;
also bug#2666). It makes it difficult to write doc-strings for 'regexp
defcustoms, as we see in both of these cases.

Yes, but that's not what the doc says people should type, and IMO
"ctrl-q ctrl-j" is a lot more confusing than "\n", especially in an
interface that is supposed to make life easier.
